This document discusses Management By Objectives (MBO), an approach developed by Peter Drucker. MBO involves managers and subordinates jointly defining common goals and areas of responsibility. They use agreed upon measures to guide operations and performance assessments. The MBO process includes goal setting, implementation of plans, and review/appraisal. Benefits include a results-oriented philosophy and improved planning/morale. Challenges are that MBO can be time-consuming and create organizational problems if not implemented properly with support, training, commitment and realistic goals. Examples of companies using MBO include Xerox, HP, and DuPont.
